Aperture does not support AVCHD2 format that the G6 record. That's because is not a standard. If you want to store your videos in the same library, without any loss in quality, use a little free software called Remux beta. It remuxes your avchd files to m4v or mp4 without any loss in quality. It only takes 2-3 seconds per clip to convert. It supports batch conversion. It does not recompress your files, it's just changing the comtainer type for the video files, because inside all formats are H264 encoded.

Something odd with all this. Just checked the video clips I took last Sunday for the format. They are, as I thought, AVCHD HD 50p, and they upload and play with no problem in iPhoto. If it handles European 50p, it should handle American 60p just as well should it not?

I'm just wondering whether the OP has a computer that is pre-Intel?

Edit. You've got me wondering now whether the clips are HD Lite or full HD. The camera doesn't go into that much detail in its playback data.

No problem with AVCHD video files in iMovie, LightRoom, etc. Have never tried in Aperture and don't plan on it. These are files from a GH2, Sony A33/65/77, and a interlaced files from a Pany camcorder. My 1080/60 files are from a GH3, which are not wrapped in AVCHD.

have also stayed away from iMovie, as i had an older version that took forever to upload movies (probably my older computer's fault). maybe that is a solution? or is iPhoto preferable - have you had success with iPhoto and 1080p 60fps?

New version of iMovie with Mavericks, too. I haven't tried it but supposed to deal with AVCHD nicely. I tend to shoot MOV.

Sorry, yes the clips that have uploaded to iPhoto are 1280x720 50p, not Full HD.

I shot at the highest quality this morning and, infuriatingly, it doesn't transfer to the iMac. I'll try the same with my Sony camera some time today.

Oddly and probably not related to the above, when I connected the camera to the iMac this morning, it tried to transfer four duplicate video clips to the computer. It has not tried that before and I connect and transfer images regularly. The 16gig card has about 13gig of images and video, mostly stills on it.

That is because 1080p50 is not a standard, there is only 24p, 25p and 30p. 720 is a standard up to 60p. Panasonic and Sony are on their own with 1080 50p and 60p. Remux beta is a quick solution for this, it converts them instantly in mp4 or m4v in just a few seconds, with no loss in quality.

just downloaded remix beta today - worked as advertised! thanks for the tip - until aperture supports the native panny 60fps files, i will likely go this route. not one stop shopping, but not too inconvenient either....

I've just experimented a bit with these 50/60p movies on both my Panasonic and Sony cameras. Using Finder, I find the clips in the camera's AVCHD folder [on the card obviously] and just clicked to open them in Quick Time. They open and play with no problem. Then I just opt to Save and rename them in a folder I've created especially for them on the desktop. I can open this folder like any other and click on the clips to open them in Quick Time. They appear to be saved as .mov files.

thanks d3xmeister - tried remux beta out and worked just as you said. until aperture supports native 1080p 60fps files, this is a good and not-too-inconvenient solution. thanks! and thanks to all who were kind enough to weigh in.
